Fender

ABSTRACT

THE PRESENT INVENTION RELATES TO A FENDER CONSTRUCTED BY BORING A RUBBER PLATE HAVING A BASE FIXTURE WITH A LARGE NUMBER OF HOLES AT APPROPRIATE INTERVALS RUNNING IN THE DIRECTION FROM A CONTACT SURFACE OF THE PLATE TO A FITTING SURFACE, SAID FENDER TO BE FITTED TO THE WHARF SIDE OR SHIP&#39;&#39;S SIDE FOR THE PURPOSE OF PROTECTING THE SHIP&#39;&#39;S HULL.

E02b 3/20U.S. Cl. 61-48 5 Claims ABSTRACT OF THE DISCLOSURE The present inventionrelates to a fender constructed by boring a rubber plate having a basefixture with a large number of holes at appropriate intervals running inthe direction from a contact surface of the plate to a fitting surface,said fender to be fitted to the wharf side or ships side for the purposeof protecting the ships hull.

BACKGROUND OF THE INVENTION The fender in use is fitted to the wharfside or ships side, but more often to the wharf side. The conventionalfender is usually formed like a pillar and this pillar-fender contains alongitudinal cavity, which does not open on the Contact suface whichengages the ship. With good absorption of impact energy, the fender ofthis type has been increasingly preferred in use, but it has thedrawback that its contact surface on the ships side is limited. Thisdrawback is compensated by applying various separate members to thiscontact surface.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to afender to be used for protecting a ships hull.

The primary object of this present invention is to provide a fender withan enlarged ship contact surface area assuring excellent absorption ofimpact energy. The conventional fender heretofore used in itself has anarrow ship contact area and it occasionallygives a dent to the shipshull. In the present invention, the ship contact area is enlarged toeliminate this drawback of the conventional fender heretofore known.

A second object of this present invention is to provide a fender whichis applicable regardless of the ships size.

A third object of this present invention is to provide a fender, simplein structure and easy in manufacturing, that can give the abovementionedeffects.

The objects and effects of this present invention will be betterunderstood from the following description of an embodiment.

FIG. 1 shows a fender of this present invention as viewed from thecontact surface which engages the ship,

FIG. 2 shows a section along the line lI--II of FIG. 1,

FIG. 3 is a contact surface view of amodied form of the fender,

FIG. 4 is a cross-sectional view taken on line 4-4 of FIG. 3, and

FIG. 5 is a contact view of a further modified form of the fender.

On a circular resilient rubber plate 2 having a base mounting lfixture 1are bored a plurality of hexagonal pillar holes 3,3' starting from aship contact surface 7 ice and running to said base fixture 1 and atappropriate intervals. In said base fixture 1 an iron plate 4 isembedded parallel to the wharf fitting contact surface against the wharfand at the same time an insertion hole 6 for a bolt 5 is provided in thebase, said bolt 5 being driven into the wharf side is put into saidinsertion hole 6; and then a nut is screwed onto said ybolt forfastening. The ship contact surface 7 is realtively large.

The FIGS. 1 and 2 illustrates only as an example, hexagonal holes 3,3being bored in the circular rubber plate, but the holes can be circularas shown in FIGS. 3 and 4, triangular square as shown in FIGS. 3 and 4or polygonal other than hexagonal. The large number of holes 3a runningtoward the wharf contact fitting surf-ace may be through holes as shownin FIGS. 3 and 4.

The assembly is a rubber plate 2 bored with many vertical or verticalholes 3,3 and 3b through holes 3a to the wharf side, appropriatelyspaced from each other.

A fender of the above construction is mounted vertically to the wharfside by means of the insertion holes 6 of the fender 2.

When a ships hull comes into contact with the external contact surface 7of this fender, this fender comes into contact With the hull over a verysapcious area instead of the narrow area in the case of a conventionalfender as heretofore known, so that the hull is not damaged; thereby theholes 3,3 and 3b or the through holes 3a running from the external shipcontact surface 7 to the fitting surface 1 against the wharf can absorbthe strain of the rubber plate 2 due to the contact evenly over theentire surface of said plate. And this effect will be exhibitedreagrdless of the ships size. Said iron plate serves to preserve theconfiguration of the fender and strengthen the fixture.

I claim:

1. In a wharf fender for ships, a substantially flat base fixture, arelatively thick resilient rubber plate having a. large ship engagingsurface, a fitting surface engaging said base, said rubber plate beingprovided with a plurality of parallel bores extending through itsthickness from its ship engaging surface and being open at said shipengaging surface, a reinforcement plate embedded in said base fixtureand extending parallel to the wharf engaging surafce of said basefixture and retaining means adapted to be fastened to said base fixtureand said rubber plate for holding the same against a wharf side.

2. A fender according to claim 1, said bores extending through said baseand said plate from the ship engaging surface to the wharf engagingsurface.

3. A fender according to claim 1, said bores being hexagonal.

4. A fender according to claim 1, said bores being polygonal other thanhexagonal.

5. A fender according to claim 1, said bores being circular.
